Australian Task Force (1 ATF) was located at Nui Dat in
Phuoc Tuy Province, South Vietnam from April 1966 to October
Headquarters (HQ) of 1 ATF commanded
the Task Force which included infantry battalions (three
from December 1967), special air service squadron (SAS),
artillery regiment, armoured squadron (from February 1968),
cavalry squadron, signals squadron, and other supporting
arms and services. By December 1968 the approved
establishment for HQ 1 ATF was 35 officers and 150 other
ranks to plan and control operations.
During the war HQ 1 ATF deployed away from the Nui Dat
base in support of operations, starting late 1966. At
this time, the enemy had been blooded at the Battle of Long
Tan. The Nui Dat base was well developed and Tactical
Area of Responsibility (TAOR) was under constant patrolling
and secured, allowing the Task Force to move further away
from Nui Dat into its Area of Operation (AO). However,
until the Task Force manpower was increased to three
battalions in December 1967 deployments remained within the
The first forward deployment of HQ 1 ATF Main, away from
the Nui Dat base area, occurred on Operation (Op) Hayman in
November 1966. This was also the first full scale airmobile
combat assault into unsecured Landing Zones (LZ) by the
Australians. The area of operation was Long Son
Island, which is just off the coast to the West of Baria and
surrounded by swamp.

103 Sig Sqn (39 personal) deployed the communications to
support the HQ, which included a Signal Centre (SIGCEN),
Telephone Switchboard (Ebony Forward) and the Radios, all
housed in 16’ x 16’ tents. Telegraph and cipher
equipment for the SIGCEN was carried in a Landrover loose
and then setup on tables for use. Radio sets were
remoted to the TOC. Detachments from 145 Sig Sqn (4
men) and the US Army 53 Sig Bn (10 men) provided rear links
by both Radio Relay (RR) and High Frequency (HF) Radio to HQ

By middle 1967, HQ 1 ATF Main and
now 104 Sig Sqn, started deploying further away from Nui

Armoured Personnel Carriers (APC), if the situation called.
staff and signals had concerns with the HQ 1 ATF deployment
arrangements because of the time to setup, protection for
the staff and communication equipment. In July 1967,
on Op Paddington the Australian HQ deployed with the US
Army, including the 11th Armoured Cavalry Regiment (11 ACR)
and saw first hand how the American Army deployed. The US
Army used Armoured Command Vehicle (ACV) Type M577 for
Command Post (CP), which was a variant of the APC M113
series used by A Sqn, 3 Cav Regt at the time in the Task
The M577 had
its hull height extended so that its occupants could work in
relative comfort. These vehicles contained a number of
radios and map-viewing facilities. To facilitate the number
of radios operating in the ACV, a generator was mounted
above the engine deck, opposite the driver's compartment.
A tent was carried on the top rear and attached directly to
the rear of the track to provide greater work space.
Multiple ACV’s could be connected via the tents forming a
larger operations centre. They were usually armed with
a single, pintle-mounted Browning L3A4 (flex version) .30
caliber machine gun, but a 7.62mm GPMG M60 machine gun was
sometimes mounted as an alternative.

In fact, the Cavalry Squadron HQ had
one ACV, Callsign OA (ARN 134456) which was the OC’s
vehicle. This vehicle allowed the Task Force to test
the HQ requirement and was used as backup for the Task Force
CP during high threat periods at Nui Dat. In late
1967, HQ 1 ATF made a request for four M577A1 vehicles, with
crews, for its HQ deployment requirements.
HQ 1 ATF CP concerns were
highlighted and addressed in a paper by the OC, 104 Sig Sqn,
Major Gerard Lawrence in November 1967. Lawrence’s
The communication systems and main
CP layout have undergone a number of changes resulting from
the different ways in which new members of the G staff wish
to work and from changes in requirements. The present
arrangements seem to work reasonably well. No
significant improvement seems likely without a radical
change in concept.
The use of ACV’s as the basis of a forward HQ should
enable the HQ to be more quickly established and will
eliminate the need for emergency forward HQ. In most
circumstances it will still be necessary for radios to be
located at the best communications site and operate
remotely. An intercommunication system will be

became routine in the first half of 1968 and further away
from Nui Dat. Op Duntroon (Jan), Op Coburg (Feb) and
Op Toan Thang (Apr/May/Jun).
Another ACV, Callsign OC (ARN
134459) arrived with C Squadron, 1 Armoured Regiment (Tank
Squadron) in February 1968. This ACV was equipped with
both American and British Radio Sets and was used for
command and control. This was important as the
Centurion Tanks only had the British Radio Sets and were not
compatible with the Task Force Radio Nets, which used only
the American equipments.
On Op Toan Thang at Fire Support
Patrol Base (FSPB) Coral in May 1968, the deployed
Australians along with its Task Force HQ and supporting
Signals came within an ace of being wiped out by the North
Vietnamese Army. The HQ was most vulnerable and the
complete command, control and communications had to be dug
underground in bunkers. This took a number of days
which was handicapped by enemy action, limited defence
stores and poor weather.

supplied by Graham Arnold.
After this action, now known as the
Battle of Coral, the four ACV’s that had been requested in
1967 were urgently demanded by HQ 1 ATF.
The four ACV’s were available in
Australia but were missing some radio equipment. HQ 1
ATF requested the vehicles be forwarded to Vietnam less
missing radios. This would in the following years
cause the Q Staff many problems in accounting but four ACV’s
were shipped on MV Jeparit (Trip 17) in August 1968 and the
vehicles arrived in Vietnam in September and were quickly
moved to the Task Force for service.
Callsigns (85) were drawn from the Cavalry Squadron radio
net, in particular its Support Company Troop. APC
vehicles in this troop were predominantly M125A1 mortar
carriers and were grouped in sections which carried
Callsigns 81 to 84 and 85 was the next for assignment.
The first deployment of the HQ 1 ATF
Main using ACV’s was on Op Capitol at FSPB Lion in early
November 1968, as follows:
Callsign 85 (ARN 134469) – Operations
Callsign 85A (ARN 134470)

The use of ACV’s for the HQ functions was very successful
and a fifth HQ 1 ATF ACV was added Callsign 85D (ARN 134472)
in April 1969 for use by the Task Force Intelligence Group,
including 547 Sig Tp in its Signals Intelligence (SIGINT)

ATF was approved and issued by Army Office for the first
four ACV’s along with some additional manpower in December
1968 with the fifth approved in April 1969. Later the
ACV’s were to be transferred to the Cavalry Squadron
establishment to ensure their maintenance.
All the APC’s and the ACV’s in
Vietnam undertook belly uparmouring in late 1970 as a high
priority to decrease vehicle and personnel casualties
suffered for enemy anti vehicle mines.

With the Cavalry Squadron fostering
the HQ ACV’s, they remained in service until the end of Task
Force operations in Vietnam late 1971. Callsign 85,
85A, 85B and 8D were manned by the HQ Staff and left Nui Dat
on the 16 Octocter 1971, redeploying to Vung Tau. The
last 1 ATF vehicle to leave Nui Dat was Callsign 85D with
its two 547 Sig Tp operators. However Callsign 85C
with its 104 Sig Sqn detachment remained until the 7
November 1971 supporting the 4RAR/NZ (ANZAC) Group, the last
Australian troops to leave the Nui Dat area.

OC, 104 Sig Sqn, Maj Norm Munro wrote in the June 1968
1 ATF is ultimately to be issued
with four tracked Armoured Command Vehicles (ACV) for use at
a forward HQ. A request has been submitted for
allocation of one ACV as the forward Signal Centre vehicle.
It is proposed that the ACV be fitted out with two TT/TA-TG,
one TT-76/GGC-3 and associated equipment, two RS AN/GRC-106
and two KW-7. This will enable a secure RTT circuit
(HF) to be established between Main and Rear HQ immediately
the HQ deploys. Following establishment of normal RR
system the HF link would serve as the back up to the RR.
Maj Munro confirmed in his July 1968
monthly report that HQ 1 ATF has agreed to 104 Sig Sqn
getting an ACV for the forward Signal Centre.
In his October 1968 monthly report,
Maj Munro reported that ACV had been received and was being
fitted out as follows:
- AN/GGC-3, TT-4A/TG, 2 x TH5/TG, 2 x TA/182-U for
Duplex Radio Teletype (RTT) circuit HQ 1 ATF Main to HQ
1 ATF Rear (Nui Dat).
- TT 4A/TG, TH-5/TG, TA-182/U – Simplex RTT Circuit HQ
1 ATF Main to HQ 1 ATF Rear (Nui at).
- 3 x KW-7 (cipher equipment for the telegraph
- AN/GRC-106, AN/PRC-47 – HF RTT/CW/Voice as required.
- 2 x SB-22/PT – Ebony Forward Switchboard.
- Radio Set AN/GRC-125 – VHF Voice.
- One commercial 6000 BTU/Hr air conditioner.
On the first deployment to FSPB
Lion, John Koosache can remember sitting in the SIGCEN ACV
on the code box with a red grenade in his hand with the
instructions 'if this thing hits a mine or is .... attacked,
pull the pin and get out the best way you can'. Obviously
John did not have to blow the codes and this was his last
job outside the wire.

Normally the telegraph circuits were
connected via RR circuits, with the HF Radios remaining as
backup. Small changes were made to the equipment
configuration over the following years, including a SB-86/P
Switchboard replacing the SB-22/PT equipment and a VHF
Teletype link for the last deployment in Oct/Nov 1971.
The KW-7 Crypto equipment caused lots of problems to the
communicators, as it did not handle the heat and normally
had a fan blowing air over the equipment.

I worked out of the ACV at FSB Julia and
FSB Kerry during 1969, including brewing up our own
specially sourced ground coffee, which Brig Sandy Pearson
would come over late at night to cadge a pannikin from us
whilst we told him what was really happening around the AO.
I subsequently obtained a licence to drive the sucker and
have the dubious distinction of nearly drowning it in the
Nui Dat Dam during an exercise we had to put on within the
wire of 1 ATF to show the incoming Brigadier how we
operationally deployed. The bloody tankies had omitted

experience at a FSPB and the SIGCEN ACV;
It was late
February 1969, I had just arrived in country and had spent
one day in the SIGCEN at Nui Dat and was told the next
morning to get my gear as I was going to the 104 Sig Sqn
Forward SIGCEN with HQ 1 ATF at FSPB Kerry.
When I got there, I couldn't believe
how I had got myself into such a mess. I was just
completely unprepared for constant heat, dust, artillery
fire, sleeping in a hole in the ground, cocked rifle on my
first clearing patrol which almost ended in disaster when
the signalman behind me forgot to remove his magazine, when
we came back through the wire and there was this almighty
bang! I just about shit my pants on the spot.
Fortunately he had pointed his SLR to the ground.
Then came my night in the SIGCEN.
It was the ACV Callsign 85C. I was working by myself
and like a cat on hot bricks. At about ten o’clock I
got a call from the SIGCEN at Nui Dat. They said they
were ready to do a ZNP4. I said "mate, what the fuck
is that?” The irate reply that I got was,"its a key
change you stupid bastard, didn't they teach you anything at
Balcombe. O the ignominy of it all! Off course
it was the key change on the KW-7 in the ACV.

solution of couriering SIGINT forward by a 547 Sig Tp
officer, normally by helicopter, with classified papers and
a thermite grenade, became a problem, following an
incident with 9 Squadron RAAF, in early 1969. It
became evident that the carriage of classified information
by helicopter to any forward base introduced operational and
The OC, 547 Sig Tp, Major Steve Hart, was
confronted with a requirement for a new way to get
classified SIGINT timely to the SO2 (Int), when he was
deployed with the Commander at HQ 1 ATF Main.
The solution was to use a channel on the
RR and terminate it on a Telegraph circuit protected with
KW-7 equipment using exclusive cipher keys, all installed in
an ACV for the exclusive use of the SO2 (Int). 547 Sig Tp
manned the equipment at both ends and this also allowed the
unit to deploy operators forward to monitor enemy
transmissions from the FSPB.
Until the ACV Callsign 85D materialised
in late April 1969, 547 Signal Troop did get an immediate
loan of a M113 from the Cavalry Squadron
as an interim solution.
Brown gives an overview of how the ACV was used;
When we initially started to deploy
to FSPBs using Callsign 85D we were totally reliant on 110
Sig Sqn and their AN/MRC-69 equipment to provide the radio
bearer path for our telegraph traffic between the FSPB and
the 547 Sig Tp Comcen at Nui Dat.
was a totally unsatisfactory arrangement because the radio
bearer had frequent outages, and when it was up, the signal
was so marginal that we continually ended up with corrupted
(read unusable) traffic which had to be re-sent; re-sent;
re-sent. This to a degree negated the real time value
of having SIGINT Operators on the ground at the FSPB.
advent of the ACV gave us the opportunity to look at an
alternative radio bearer path which, hopefully, would be
both easy to transport into site and easy to set up.
Because most of our TAOR was reasonably flat and generally
suitable for VHF line of sight from FSPB to HQ 1ATF Rear,
John Harding and myself decided to explore the viability of
utilizing the RT-524/VRC transceiver as our bearer. We knew
that the transceiver itself was a robust and extremely
reliable unit but we had some concerns that it may not
handle a higher transmission ratio above the normal 1 – 10
transmit – receive cycle.
turned out that the RT-524/VRC was perfect for the task.
After a lot of trial and error we came up with a standard
ACV fit-out comprising Kleinschmit teleprinters connected to
TSEC/KW-7 crypto gear (mounted on incendiary slabs) which
was connected via a TA-182/U tone converter and TH-5/TG FSK
unit to the RT-524/VRC transceiver, which itself was
connected to a RC-292 antenna. It was all standard
equipment except for a resistive attenuation pad we had to
knock-up to match the TH-5/TG output to the RT-524/VRC
input. We used the same setup at the Nui Dat end with the
RC-292 antenna mounted on top of the 72ft DECO mast.
We also installed HF equipment in
the ACV for intercept tasks. These were Racal RA-329
units which comprised a Racal RA-217D HF receiver and Racal
MA323 FSK unit mounted in a “ruggedised” casing.
the ACV deployed, it also took a 10KVA generator and 16
jerry cans of fuel. This made for a decidedly uncomfortable
trip for the troopies who were conveyed out to the FSPB on
the ACV because the jerry cans had to be stowed on top of
the ACV and the troopies had to ride outside the ACV perched
on top of the jerry cans – that certainly increased the
“pucker factor” by a few degrees.
summary, notwithstanding the necessity for the Cav crew to
drive the ACV, 547 Sig Tp was able to deploy a totally
independent sub unit which was able to sustain intercept
operations in the FSPB environment while maintaining (most
of the time) ZBZ5 secure telegraph traffic back to base.
Another good example of the Troop’s collective ingenuity
serving to get the task done.
until I left in Aug ’70, I know we lobbied to have some 547
members trained to drive the ACV (even if only in Nui Dat)
but unfortunately it never happened – we were allowed to
power it up – and drop the ramp – but we weren’t allowed to

SIGINT operators and Callsign 85D went missing after the
convoy they were travelling in from FSPB Picton came under
“On the 8 December 1969, we are all
of a sudden "missing" - bit hard to 'miss', but that's when
the Boss found out what happened, and the orders were 'don't
care how you do it, just get them out of there'-- OK for
him, he didn't have to follow the only surviving Centurion
in low low gear, trying to bask it's way through the
boonies, with all us dickheads sitting on top of it ---
never was fond of that rule !!!”
The 547 Sig Tp members and their ACV
made it out safely but sadly two Australians were KIA and
two WIA in the convoy mine ambush with an APC (Callsign 23A)
heavily damaged. Also a Helicopter attempting to land
to effect dustoff of the injured, detonated another mine
resulting in another WIA and a badly damage Huey.
In should be noted that the vehicle
generator was petrol and all the jerry cans were full of it.

Return to Australia (RTA)
104 Sig Sqn’s OC plus 60 embarked on
HMAS Sydney for the return trip to Australia on the 6
November 1971. Radio Operators doing Liaison Officer
(LO) radio tasks returned to Detachment 104 Sig Sqn at Vung
Tau in November to help complete cleaning and packing of the
unit stores for RTA.
104 Sig Sqn’s return to Australia
was completed in late Dec 1971 without its ACV and it would
take a few years for the unit to be reunited with a number
of the vehicles.
On the 13 December 1971, 547 Sig Tp
ceased operations from their Vung Tau location and on the 23
December 1971 in the early hours boarded buses for the
airport to start the journey home to 7 Sig Regt, Cabarlah.
Post Vietnam would see Electronic Warfare (EW) developments
and a special signals field force squadron (72 EW Sqn) to
support future deployments.
During December 1971 to February
1972, HQ 1 ATF was primarily concerned with maintaining the
security of the Vung Tau base and continuing the preparation
plus dispatch of personnel and equipment to Australia.
All vehicles were steam-cleaned after washing to fumigate
them, in line with the Australian quarantine rules.
The last 1 ATF troops including 110 Sig Sqn (doing both TF
and Force RASigs roles since early November 1971) boarded
HMAS Sydney Voyage 4 (South) for the trip home to Australia.
Included in the stores were the last armoured vehicles, ten
M113A1 APC, two M125A1 81mm Mortar Carriers and one M577A1
ACV. The Vung Tau base was handed over to the
Vietnamese on the 29 February 1972.
